How does caching work?

#1
Hi,

I can't help but notice: webroot\internal_data\page_cache

What's in there? Is this how xf caches stuff? How does using APC changes that behaviour?

... so many questions :)

I see, it's a shame none of this seems documented anywhere. Going through the code is not the most efficient way to learn how xf function. Hopefully they can change that in the future.
